' To all whom it may concern:

Be it known that I, GLENN G. GREENE, a citizen of the UnitedStates of America, residing at Warren, in the county of Warren and State of Pennsylvania, have invented certain new and useful Improvements in Casters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in casters and particularly to improvements in casters of the pivot-bearing type; and an object of this invention is to provide a caster of this kind with hearing means arranged to engage the inner wall of the hollow leg of the bed, so that the caster will not be easily displaced from within the bedstead-leg, when the caster or leg strikesagainstv an obstacle. v

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure 1 is an elevation, partly in section, of my new caster in place within a bedsteadleg; and Fig. 2 is a section on the line AA of Fig. 1.

The caster a is provided with a casterwheel 6 rotatably mounted upon the axle '0 carried in the lower end of the cheeks or jaws d. From the yoke e there rises the pintle f the upper end 9 of which is pointed to form a pivot. Upon this pivot rests the lower face of the centrally-disposed rivet or fastener h which fastens together the plates z, j of the disk 70. The leg-supporting disk m is dished upwardly atm' and is formed with a flange n which lies outsideof the dished portion and upon which the lower end of the bedstead-leg 0 rests. Struck up from the dished portion m of the disk m are a series of lugs p the free ends of which bear against the inner wall of the bedstead- Specification of Letters Patent. I.

leg, when the latter is supported in place upon the flange or ledge 11.. The disks in, m,

are connected by av Wire-frame comprising several U-shaped pieces of wire one leg 9 of whichconnects the two disks in, m and the other leg 7" of which is free and bears're thereof, these U-shapedspringmembers lie T wholly on one or the other side of this vertical axis, as is clearly shown in Fig. 1.

By the provision of the lug 12, there is. obi tained a bearing of the leg-supporting disk of the caster against the inner wall of the bedstead-leg; and this bearing" prevents the accidental displacement'of the caster, when either the. latter or the bedstead-leg strikes an obstacle. I

I claim: A caster comprlsing a caster-wheel; a

yoke having jaws which carry said caster wheel; a pintle which rises from said yoke; a spring-frame the free ends of which bear frictionally against the inner. wall of the bedstead-leg and hold the caster friction ally in place; and a leg-supporting plate which carries said spring-frame and is "dished upwardly and from which are struck up lugs; said plate being adapted and arranged to support the bedstead-leg and said lugs being adapted and arranged to bear against the inner, wall of said bedstead-leg and to resist. displacement of the caster therefrom.
